当我使用某些数据初始化ArrayStore时,我可以插入新记录并且所有内容都正确显示。但是,如果我使用空数组初始化ArrayStore,那么当插入的第一个记录工作时,每个后续插入都会覆盖网格中的第一个记录。 这似乎是一个简单的问题,但我找不到一种将网格初始化为空的工作方式。
那么我做错了什么?
非常感谢提前!
var myData = [
// Initializing with the following element works.
//['Hyannis Connector',3456.9,'Hyannis Connector Bridle Path','Hyannis Connector/Baden Powell'],
// Initializing with this element works but leaves an empty row in the grid..
//[]
];
// create the data store
segmentStore = new Ext.data.ArrayStore({
fields: [
{name: 'trailName'},
{name: 'segmentLength', type: 'float'},
{name: 'startJunction'},
{name: 'endJunction'},
]
});
// manually load local data
segmentStore.loadData(myData);
// create the Grid
segmentGrid = new Ext.grid.GridPanel({
region: 'south',
store: segmentStore,
columns: [
{header: 'Trail Name', width: 140, sortable: true, dataIndex: 'trailName'},
{header: 'Segment Length', width: 75, sortable: true, dataIndex: 'segmentLength'},
{header: 'Start Junction', width: 75, sortable: true, dataIndex: 'startJunction'},
{header: 'End Junction', width: 75, sortable: true, dataIndex: 'endJunction'},
],
stripeRows: true,
height: 150,
width: 600,
title: 'Trail Segments in Route',
layout: 'fit'
});
var defaultData = {
trailName: segment.getTrailName(),
segmentLength: segment.getLength(),
startJunction: '',
endJunction: ''
};
var recId = 3;
var p = new segmentStore.recordType(defaultData, recId);
segmentStore.insert(0, p);
答案 0 :(得分:-1)
答案在ExtJS论坛中提供。 我需要确保新记录的记录ID不同。
